IoT Time Series Aggregates Service – Selecting

Select Syntax

With the optional select parameter one can define which data to return. The value of the select parameter is a comma separated list of requested data. Each value in the list can either be a variable name or an aggregated field using a variableName.fieldName syntax. The field name can be one of the following:

  • countgood
  • countuncertain
  • countbad
  • sum
  • average
  • mintime
  • minvalue
  • maxtime
  • maxvalue
  • firsttime
  • firstvalue
  • lasttime
  • lastvalue
  • sd

If no select parameter is specified, all variables and fields are returned. If a variable is specified, but no field name, all the fields for that variable are returned. If a variable and field name are specified, only that field of the variable is returned. Variable names are case-insensitive.
